So...first thing this morning, I reinstalled the newly restuffed power supply electrolytics:

I also installed four new rectifier diodes. And for good measure, I also replaced the snubbers (0.22 uF, 250 VDC), C180 and C181. These are the two burgundy items to the left of the new diodes that look like Chiclets.
I then proceeded to replace as many of the electrolytics under the chassis as I could.
The result:

No, the 470 uF 50 VDC electrolytic did not get replaced - I forgot to order one. Perhaps in the near future, I will go back in and take care of that.
I also replaced the death caps with new X-Y safety caps.
Finally, I put the bottom and top back on, and reinstalled it in its cabinet. I then lugged the heavy thing upstairs and installed it on my home office desk, replacing the Sansui 2000:

I will replace the lamps with LEDs in the near future as well.
But for now...that is it for this S-7900A. With this receiver, I can now sort of relive my younger years, remembering how much I enjoyed the S-8900A (FM only) that I owned back then.
